, invention relates .to' sucker rod elevators. I V

Y I In accordancewith my 1nvent1on,'a sucker rod elevator is produced,- embodying a body 1 portion having a recess or opening'to receive the sucker rod.v The sucker rod is held with i in'the recess by means'of a latch element or latch elements, movable acro'sstherecess or opening. The body portion is pivotally susq pended from actuating members,in turn supported by a bail or the like Means are pro-' vided wherebythe latch element or elements are automaticallymoved inwardly when the supportingactuating members are swung to an upstanding position "with relation to the body portion. When the "supporting actuating' membersare thus'shifted to the upstanding position, they are automaticallylocked against further turning movement-with reg o lati on to the body portion. The device is strong, durable, and easytooperate. f 1

In the draw1ngs,wherein, for purpose I of illustration; isshown a preferred embodiment of my invention, the numeral '10 desig 1n ate's the body portion of the sucker rod ele- PE-ach' sleeve 16' is Figure 5 is a similar view, with the sup-- porting actuating me bers shifted to thever preferably rounded at 13'. Preferably formed integral with the opposite sides ofthe body portion '10 are trunnions 14, as shown.- I The-numeral 15 designates a pair of supporting actuating members, embodying sleeves 16, carrying pairs of spaced l -nuck les 17 'Ihese sleeves are pivoted upon the trimnions 14, anol are held thereon by pins 18'or the like. 2 1 Coacting with the supporting actuating members 15 is 1a bai'l 19 rovidedat its lower endwith eyes 20, arranged {between the knuckles 17 and pivoted thereto, by pins 21 orthelike. I

walls 24 jand25; '.Thejaw s 1-2 are provided near their outer ends with transverse openings 26, receiving sliding latch elements or v bolts 27, having heads 28. These latch elementsare automatically shifted outwardlyby means'of compressible coil springs 29. The 1 I outer ends of the latch elements or bolts :27 i

and their heads 28 project into the recesses '22, and theheads 28 engage'the' cam-faces 23,

- tion 'to the body portion 10 and engage the end 3 i V stop-walls '24, when the members 15 are shift= ed to the relative vertical posit-iomthus limiting the extent of swinging movement'of such,

members-15 'l Means are provided to lock the supporting i actuatlng' members 15 to the body portion 14 ,v against swinging movement, when they w are shifted to the upper vertical position, with relation thereto. This locking means embodies, a pair of'lo'cking bolts. or elements '30, slidable within recesses 31,;formed in lateral extensions 32, of the sleeves 16. The 7 locking bolts'BO are urged outwardly by com pressible coil springs-33.; When projected,

the locking bolts 30enter recesses 34,- formed j provided upon fits' inner 3 s de. with a recess 22, extending throughfthe 770 -inner sidefthereof and affording an inclined Y cam face 23;andalso providing end stop; I

in the rear end or face of the body portion 10. The outer ends of the locking bolts 30 are arranged to be engaged by a retracting element or lever 35, pivoted to the body portion 10, as shown at 36, and having cam ends 37, to engage with the locking bolts. A knob 38 is attached to the retracting element 35 to manipulate the same. The retractingelement 35 is positioned between horizontal I flanges 39, formed upon the rear end ofthe body portion 10, at-the top and bottom thereof. f

The operationof the elevator'is as follows: hen the supporting actuatlng members are shifted to the relative horizontal posltion, the stop end walls engage the heads 28 of the latch elements'27, and these latch elements are automatically shifted to the outer position, by means of the springs 29. The sucker rod may now pass intothe recess 11. The supporting'actuating members 15 are now shifted to the relative vertical position, extending above the body' portion 10, whereby the latch elements 27 are projected into the recess 11,7to retain the sucker rod therein. v r

' The heads 28 now engage the end stop walls 24. At this time, the lockingbolts '37 are projected into the recesses 34, by the springs 33, and hence the members 15 are locked to the body portion 10, against turning movement, ineither direction, by theend stop walls 24 and the lockingbolts 37. By swinging the retracting element upon its'pivot,

the locking bolts .37 may be retracted, and the members 15 shifted to the relative horizontal position, as explained. 7

It isto be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that Various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit, of my invention, or the scope of the subjoined claims.
